Messaging-App (In Progress)

A simple Messaging App that I developed to practice my knowledge on:

• Java FX
• Python
• Database Connectivity
• Encryption with C++

Key features

• Creating an account
• Add other users from the database
• Exchange messages with your contacts

Usage

• After running the App:
  • If you already have an account
    • Login using your credentials
  • If you use the app for the first time
    • Register by pressing the "Register" button
    • Create a unique username and a secure password
    • Press the "Back to Login" button to return to Login Page
    • Login using your newly created credentials

• After connecting to your account you can:
  • Add other users using the search bar on the top left (make sure to type the correct username)
  • Select contacts
  • Send messages

Installation

1. Download Java and Python

Navigate to the project folder in bash

• Java:

sudo apt update
sudo apt install openjdk-21-jdk

• Python:

sudo apt update
sudo apt install python3

2. Download Flask and Flask-Cors

Install pip

  sudo apt install python3-pip

Create a virtual environment

   sudo apt install python3-venv
   python3 -m venv env_test
   source env_test/bin/activate

Install Flask

   pip install Flask

Install Flask-Cors

   pip install Flask-Cors

3. Download JavaFX (Same version as Java)

• Download JavaFX from GLUON
• Extract the zip
• Copy the path to the lib folder
• Write the following command with Path_to_javafx-sdk-23.0.2/lib beeing the path to the lib folder of the JavaFX extracted zip file

  export PATH_TO_FX=Path_to_javafx-sdk-23.0.2/lib

4. Download GSON

wget https://repo1.maven.org/maven2/com/google/code/gson/gson/2.10.1/gson-2.10.1.jar -P ~/Desktop/JavaFXApplication2/lib/

• ~/Desktop/JavaFXApplication2/lib/ : location of cloned project

5. Compile & Run

cd src

Compile

javac --module-path /home/user/Downloads/openjfx-23.0.2_linux-x64_bin-sdk/javafx-sdk-23.0.2/lib
--add-modules javafx.controls,javafx.fxml,javafx.media
-cp ~/Desktop/JavaFXApplication2/lib/gson-2.10.1.jar
javafxapplication2/*.java

• /home/user/Downloads/openjfx-23.0.2_linux-x64_bin-sdk/javafx-sdk-23.0.2/lib :

  • Exact Path to the downloaded (and extracted) Javafx File

• ~/Desktop/JavaFXApplication2/lib/gson-2.10.1.jar :

  • Exact Path to the downloaded gson jar

Run
